Recluse Spider
The Recluse Spider (Loxosceles reclusa), also known as the Brown Recluse Spider or Fiddleback Spider, is a venomous spider native to North America.
Pronunciation
Recluse: /rɪˈkluːs/ Spider: /ˈspaɪdər/
Etymology
The term "recluse" comes from the Latin reclūsus, meaning "shut up" or "secluded", reflecting the spider's tendency to hide in dark, secluded places. The term "spider" comes from the Old English spithra, related to the German Spinne, both of which mean "spinner".
Description
The Recluse Spider is known for its distinctive violin-shaped mark on its back, which is the origin of its other common name, the Fiddleback Spider. It is usually between 6–20 mm in size, but can grow larger. The spider is not aggressive and typically only bites when threatened or disturbed.
Habitat
Recluse Spiders are native to the United States, particularly the central midwestern states southward to the Gulf of Mexico. They are often found in homes, sheds, and garages, or under logs, rocks, and debris.
Venom
The venom of the Recluse Spider can cause significant cutaneous injury with tissue loss and necrosis, a condition known as Loxoscelism. However, most bites are minor with no necrosis.
